HENRY TRENKAMP, OF CLEVELAND, OHIO.

WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 470,224, dated March 8,1892.

Application filed December lI 1890. Serial No. 373,144. (Nomodel.)

To a/ZZ whom t may concern.-

Be it known that I, HENRY TRENKAMP, a citizen of the United States,residing at Cleveland,in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in VVater-Heaters for Vaporor Gas Stoves; and l'do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

The invention relates t0 improvements in water-heaters; and it consistsin an attachment especially adapted to vapor or gas stoves, the samecomprising a device for heating water circulated through the same andarranged between the burner-tubes and the -openings for vessels on thetop of the heater, so that water may be heated while the heat used forthat purpose may also be utilized, as in other stoves, all substantiallyas shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of the rearend of a stove to which the attachment comprising the invention isfixed, as-shown in full lines. Eig. 2 is a rear elevation of Fig. l withthe curved back plate removed and the top part in section, so as to showthe relation of thel heating-tubes, the water-heater, and the openingsin the top of the stove. Fig. 3 is a plan view of Fig. l with the coversto the openings of the top removed, so as to fully disclose thewater-heater beneath. Fig. 4 is a cross-section taken on line x, Fig.

A represents the back part of a well-known form of vapor or gas stoveand provided with tube B for the distribution of vapor or gas to theburners-that is to say, either vapor produced from gasoline or the likemay be used and conveyed through tube C from a generator, or natural gasor illuminating-gas The vapor or gas flows through the tube B into thetwo parallel tubes C, which constitute the burner-tubes for thisattachment and are provided along their top with a series of smalldiagonal perforations c, through which the gas issues and burns.

D represents the attachment casing or frame, secured, as shown, to theback of the stove by any suitable means, and provided with one or moreopenings d in its top adapted to receive vessels for cooking, the sameas on an ordinary stove.

E represents the water-heating device, corresponding in one sense withthe water-back found in cooking-stoves and ranges and serving a kindredpurpose. This heater is novel in both construction and arrangement, itbeing formed, in a solid piece of casting consisting, preferably, ofbrass, although copper or other metal may be used for this purpose, andhas its water-channel cored therein, so as to aord a free and opencirculation for the water. This device is arranged horizontally towardthe top of chamber D and is formed of four or more parallel tubes e,connected at their opposite ends alternately by the short tubes e', orsuitable curved returns, so that, supposing the fluid to enter the rstor rear pipe at e2, the water will ow thence to the opposite end of saidtube, across through the connecting-tube c', and thence back through thenext tube e, and so on around until it issues out of the heater at e3,whence it is carried to the reservoir or boiler or other place wheredesired for storage or use. The four or more parallel tubes c arearranged, practically, in pairs of two or more upon either side of thecenter, and the pairs are shown here as connected by a web e4. Anopen-draft passage e5 is provided between the two sets of tubes. Uponeither side of the air-passage e5 on the two inner tubes and on theouter side of the two outer tubes are parallel vertically-inclinedflanges e6, partaking somewhat of the curvature of the respective tubesand extending upward therefrom a slight distance, so Ythat the flamewhich strikes these tubes will have a tendency to roll around the sameand be dil IOO allow sutiicient` exposure` to the dame.

Combustion is supported through the airopenings g in the bottom of the`attachment chamber, and openings h, front and rear, at the top ofthechamber afford outlets for the products of combustion, so that a steadydraft is afforded up through the attachment chamber and combustion ismade complete. The bottom of the attachment D might be entirely open;but a perforated plate at this point is preferable. It will be noticedthat the cored Water-heater is arranged horizontally, with theburner-tubes beneath the same in such relation that the flame strikesthe tubes diagonally along their bottom.

The attachment D, which contains the water-heater, and the tubes C areshown here as connected with a vapor or gas` stove; but it will beunderstood that this. attachment is not necessarily so connected andthat it` may be used separately fro m the stove, if preferred. Each ofthe tubes C has` its openings c arranged in parallel rows at an outwardangle to each other, so that while` each tube occupies a centralposition with respect to two of the parallel heater-tubes the jets ofiiame will issue diagonally therefrom against the bottom of eachheater-tube, from which pointi the flame rolls round in unbroken volumeover the side ofthe heater. Thewebse4 serve as diaphragms between theallied pairs of tubes e, and are located centrally thereof, so

that whletheyserve to connect `the saidtubes and to close the spacebetween them they also this means; at least thirty gallons of watercan-` be heated per hour, while a` full flame of heat ismaintained` forthel cooking-openings on` the top of the attachment-chamber.

Having th us@ described my invention, what ltorated burner-tube arrangedbeneath each pair of water tubes, substantially as described.

3. The water-heating attachment herein described, consisting of parallelwater-tubes having open` communication. one to the other to` establishcirculation, the said tubes connected in pairs, and the twoadjacenttubes of opposite pairs provided along their top inner portion withlongitudinal tianges on either side of the draft-space between saidtubes, in

`combination with the burners beneath said tubes, substantially asdescribed.

4. In a water-heater, a pair of parallel water-tubes e, connected at oneend by a crosstube e, a burner-tube below said tubes provided with tworowsof jet-orifices arranged so that the dames therefrom will bedirected diagonally against the bottom and toward the ou ter oppositesides of the water-tubes e, and` the flanges e6 on thesaid sides oftubes @,sub-

` Stantally as:` shown and described. By cation this. 21st day ofNovember, 1890.
